The curves of the consolidation settlement in soft clay base of flood land are gained, which compare the effect of sand drain. the settlement - time curves in different period are also gained, which increase the height of embankment to 8m, based on the test data of hang - yong highway. furthermore, the consolidation settlement characters of these entity engineering are analyzed, and, the variation rules of the rate of grade and degree of the curves in different period in the whole section, the maximal settlement and the liner regression relations between the rate of grade and degree are calculated
本文利用大變形固結有限元分析程序（ lscfea ）中的小變形平面固結分析單元（ sse2 ） ，結合實體工程項目進行了地基固結沉降的有限元計算，分別得出河灘相軟土地基在考慮砂井和未考慮砂井作用下的固結沉降曲線及杭甬高速公路試驗段在高堆載情況下的固結沉降曲線；並對以上曲線特徵進行了分析，得出各時間段曲線斜率、角度在整個斷面的變化規律，以及沉降最大值與斜率、角度變化之間的線性回歸關系。 -
The value of surplus environmental capacity of din exceeded about 70 percent of the 1st grade environmental capacity in 1997. since 1997, the impact of nutrients pollution has begun to mitigate because of the enhancing protection of marine ecology by local government. the variation of surplus environmental capacities of din and po4 - p in jiaozhou bay implicated that the discharge amounts of din and po4 - p to jiaozhou bay were bearable from late 1970s to mid 1980s
但自80年代中期至90年代中後期，營養鹽剩餘環境容量迅速減小，至1997年din剩餘環境容量已超過國家一級海水水質標準下膠州灣din環境容量約70 ，而自90年代末開始膠州灣din剩餘環境容量又有所增加，而po _ 4 - p剩餘環境容量減小速度趨緩。 -
In part four, we first advance the hypotheses, then provide some information concerning the subjects, instruments as well as the procedure of the investigation. part five concerns itself with data analysis and discussion which falls into three steps : at the outset, to understand the general distributive tendency of the data involved, descriptive analyses are made of the data concerning english learning results and language anxiety : then, t - two - tailed test is made to find out the grade variation, gender variation in english learning results and levels of anxiety ; finally, correlation analysis is conducted to understand the relationship between english learning results and levels of anxiety under discussion in respective regard
數據分析和討論分二步進行：為了解所採集到的數據的總體分佈趨勢，論文首先對農村中學生英語學習焦慮調查表的數據和農村中學生英語學習成績進行了描述性統計分析；用t雙側檢驗分析了各年級及男女生在英語學習成績、英語學習焦慮上表現出的年級、性別差異，而且，用t雙側檢驗分析了高、低焦慮組及男女生英語學習成績、英語學習焦慮上表現出的相互關系、性別差異；用圖表展示農村中學生英語學習焦慮與英語學習成績的相關關系。 -
Abstract : according to the variation in content of characteristic radioactive nuclide and the close relationship between high - grade associated elements in ore - forming components and gold, the ground gamma - ray spectrometry and x - ray fluorescence slectrometry can be used to reveal the existence of gold mineralization rapidly in field and make semi - quantitative evaluation of gold grade. this is of great significance in guiding field geological sample collection and mountain land engineering
文摘:通過測定特徵放射性核素的含量變化以及利用成礦組分中一些高品位共生元素與金密切的相關關系，可利用地面伽馬能譜與x熒光測量在現場快速揭示金礦化的存在，同時對金的品位進行準定量評價，以及指導野外地質采樣和山地工程。
